Zhong Yanghong updated KYLIN-1855: ---------------------------------- Attachment: (was: exclude_unused_joins.patch) > Should exclude those joins in whose related lookup tables no dimensions are > used in cube > ---------------------------------------------------------------------------------------- > > Key: KYLIN-1855 > URL: https://issues.apache.org/jira/browse/KYLIN-1855 > Project: Kylin > Issue Type: Improvement > Reporter: Zhong Yanghong > Assignee: Zhong Yanghong > > A cube is based on a model in which a star schema is defined. In some cases, > the cube utilizes only a few lookup tables rather than all. In this case, > when creating the sql for the flat table, those lookup tables should not be > included. Otherwise, it will confuse users when query. If users do query > according to the definition of the flat table, error of no realization will > occur due to lack of the related join. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
